Re: where is the Indication of "No fly" ?
That's normal. "Desat" has a target pressure of 105% of the surface pressure (= 5% overpressure) for every tissue, that's a much lower value than what the tissues will be able to stand at 0.6 bar. This is not to say everyone should board an aircraft right after diving, but this "take ...

Re: where is the Indication of "No fly" ?
The "no fly" time is calculated like a deco stop, with the current surface pressure as the current "depth" and a pressure of 0.6 bar as the target "surface" pressure. Thus, the "no fly" time is the time one has to "stop" at the current surface pressu...

Re: unexpected behaviour toggling aGF and back
Hi, the behaviour is as expected / programmed - although it is close to the bug or feature question. Changing the GF settings while in the dive is not covered by Erik Baker's GF concept and doing so poses a question on what to do regarding the GF low reference depth. This depth is not set by hand bu...

Re: Deco-dive with travel gas, bottom gas and four deco gases
Hi,
I will have to check the 0 m MOD issue.
All gases will be prompted for, unless they are disabled or set as lost. If they are deco, they will be prompted for once the 1st deco stop is reached on tje ascent.
Anyhow, best is always to try out with the simulator mode.

Hi, you always have to select the gases maually, either via the menu or by acknowleding the gas-switch promt, the computer will never decide on its own that you have done a gas switch without you telling the computer. --> This accounts for the calculation of your deco obligation, leading tissue, sup...

The trajectory will start with the gas tagged...

Re: Gas density threshold
Hi Michael, thanks for the post and the link to the article! The OSTC also defaults to 5.2 & 6.3 g/l as attention (yellow) & warning (red) threshold. What i was wrong with in my earlier post is that the OSTC only tracks the gas density in CC mode, not in OC. This decision was based on the fa...

Re: Gas density threshold
Hi Michel, you are right, the thresholds are independent of the operating mode. They can be changed, but only with external software (but probably that's not supported yet in subsurface / libdivecomputer etc.). Do you have a source on why OC should be more tolerable than CC? I can't really make my m...

Re: "slow ascent" indication
It just means you should ascent slowly as you did a deco dive with mandatoty stops. By no way it implies you did something wrong, it's just a reminder that your tissues are quite loaded and rapid pressure changes should be avoided.

I don't know how Garmin nor Subsurface handle in detail the end-of-deco detection.

Well, for me i still don't get the problem. As harv wrote, when the GF high was set to 65%, the re-calculation of the dives delivered 60 to 64%, and when set to 70% re-calc yielded 64 to 68%. That's a pretty good match, as wrote before, and also as the tissue conditions before the 1st dives are trac...

Re: Charge OSTC 2 from powerbank?
USB2, USB3 - that does not matter as the charger only connects to the 5V lines, not the data lines. Thus it does not do any power protocols but justs draws the current it wants to. So the more dumb the supply, the better.

Re: Difference btw Sport, 2 and Plus
The sport has an optimzed electronics and the CPU is run on lower voltage, so its base consumption is lower than with any 2 or sport. But the additional current needed to illuminate the screen scales heavily with the brightness setting and is more or less equal on all models.
